It became apparent to us that if it is possible for a tumour to grow in animal cells, then it might also occur in plant cells. To confirm such line of thoughts, we chose to research on plant physiology for the extended essay.

This project was designed to answer the question, "Can a plant equally form tumours as animals do when infected by Agrobacterium tumefaciens sp. (B6S3), and if yes, what affect does it have on plant...
